Amazon Web Services

Amazon’s Web Services is a leading cloud computing provider and has been a go-to for fast-growing web startups like Foursquare, Quora and Paper.li.

GigaOM’s Take

Although Amazon Web Services was recently in the news because of a prolonged outage, it’s still a cloud computing pioneer and arguably the most innovative cloud provider around. AWS regularly releases new features, ranging from a queue service to high-performance cluster-compute instances.
